Quizplus · Accepted Answer

Epithelial tissues are the primary tissues that line the surface of the body and serve as a barrier to microbial infection. They provide protection against mechanical injury, dehydration, and invasion by microorganisms. The skin, respiratory tract, digestive system, and urinary tract are all lined with epithelial tissues that play an important role in defense against pathogens. Muscular tissues are involved in movement, nervous tissues are involved in communication and control, and connective tissues provide support and structure.
